8. Isomers measured for a moment

PHILIP WALKER (UNIVERSITY OF SURREY)

Electromagnetic moments tell us about the distribution of charges and currents in atomic nuclei. Moments are therefore key nuclear observables for the understanding of both the collective and individual-particle properties. For experimental reasons, moment measurements typically benefit from half-lives of order nanoseconds or longer, in which case the existence of isomeric states becomes...

28. Effect of the Coulomb interaction on nuclear moments

KENTA HAGIHARA (University of Tsukuba)

Solving the Hartree-Fock-Bogoliubov (HFB) equation self-consistently with a harmonic oscillator basis, we have systematically calculated even-even nuclei with proton numbers ranging from 2 to 118 using the SLy4 parameter set of the Skyrme functional and a mixed-type pairing interaction. To investigate the origin of nuclear deformation, which is crucial in various topics such as nuclear fission...

76. PolarEx, a facility for on-line nuclear orientation at ALTO-LEB: nuclear magnetic properties measurements

Carole GAULARD (IJCLab-Université Paris-Saclay)

14/05/2025 12:00

Low Temperature Nuclear Orientation (LTNO) experiments allow us to probe magnetic properties of polarized exotic nuclei. With this technique, we observe nuclei under extreme conditions, namely very low temperatures (~10mK) and very high magnetic field (10-100T). Under such conditions, radioactive emission becomes anisotropic, and its shape provides valuable information about the nucleus...

10. Investigating the changes in nuclear structure below Z = 50 with Ag

Bram van den Borne (KU Leuven)

14/05/2025 12:20

Exploring ground-state nuclear properties is a powerful tool to investigate our understanding of the nuclear structure. Laser spectroscopy gives access to model-independent measurements of the ground-state properties (spin, nuclear electromagnetic moments, changes in the charge radius) of short-lived (≥10 ms) nuclei, providing an excellent benchmark for theoretical predictions close to magic...

24. Developments in Collinear Laser Spectroscopy at COLLAPS

Edward Matthews

14/05/2025 12:40

Collinear laser spectroscopy (CLS) is a well-established technique for observing nuclear moments of short-lived radioactive nuclei. However, sensitivity and isotope production bound the regions of the nuclear chart that can currently be explored with this method. A solution to this problem is to develop novel methods of spectroscopy with higher sensitivity. The COLLAPS experiment is pursuing...
